1. The pancreas releases a number of digestive enzymes into the small intestine. Which of the following enzymes is NOT produced by the pancreas?

• A. Trypsin (protein digestion)
• B. Amylase (carbohydrate digestion)
• C. Lipase (fat digestion)
• D. Lactase (sugar digestion)

Correct answer: D

Rationale: Lactase is an enzyme responsible for breaking down lactose, a sugar found in dairy products, and it is produced by the small intestine, not the pancreas. The pancreas produces enzymes like trypsin for protein digestion, amylase for carbohydrate digestion, and lipase for fat digestion. Therefore, the correct answer is D. Choices A, B, and C are incorrect because trypsin, amylase, and lipase are indeed enzymes produced by the pancreas for the digestion of proteins, carbohydrates, and fats, respectively.

2. In order to be included in the formation of a scientific conclusion, evidence must be:

• A. Quantitative
• B. Reproducible
• C. Obvious
• D. All of the above

Correct answer: B

Rationale: For scientific evidence to be included in the formation of a scientific conclusion, it must be reproducible. Reproducibility is a fundamental aspect of the scientific method, ensuring that the same experiment will yield the same results if repeated. This allows other researchers to verify the findings and conclusions drawn from the evidence, enhancing the reliability and validity of the scientific process. While quantitative data can be important in supporting evidence, it is not a strict requirement for evidence to be included in scientific conclusions. The term 'obvious' is subjective and does not necessarily guarantee the reliability or reproducibility of the evidence, making it an unreliable criterion for scientific conclusions. Therefore, choice B, reproducible, is the correct answer as it aligns with the fundamental principles of the scientific method, emphasizing the importance of replicating results for establishing reliable conclusions.

3. Which cavity is primarily lined by the peritoneum?

• A. Abdominal
• B. Dorsal
• C. Ventral
• D. Thoracic

Correct answer: A

Rationale: The correct answer is 'Abdominal.' The peritoneum primarily lines the abdominal cavity, providing support and protection to abdominal organs. It is a serous membrane that covers the abdominal organs and the abdominal wall, aiding in their function and protection. Choice B, 'Dorsal,' is incorrect because the peritoneum does not primarily line the dorsal cavity. Choice C, 'Ventral,' is incorrect as the peritoneum is not primarily associated with the ventral cavity. Choice D, 'Thoracic,' is incorrect because the peritoneum primarily lines the abdominal cavity and is not primarily found in the thoracic cavity.

4. Which of the following is NOT part of the circulatory system?

• A. Kidneys
• B. Heart
• C. Blood
• D. Blood vessels

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are part of the urinary system, responsible for filtering waste and maintaining fluid balance in the body. In the circulatory system, the heart pumps blood, blood carries oxygen and nutrients, and blood vessels transport blood throughout the body. Choices B, C, and D are all components of the circulatory system, making the kidneys the correct choice as it belongs to the urinary system.

5. What is the recommended daily intake of protein for adults to maintain healthy muscle mass?

• A. 0.5 grams per kilogram of body weight
• B. 1 gram per kilogram of body weight
• C. 1.5 grams per kilogram of body weight
• D. 2 grams per kilogram of body weight

Correct answer: B

Rationale: The recommended daily intake of protein for adults to maintain healthy muscle mass is typically around 1 gram per kilogram of body weight. This amount can vary based on individual factors such as activity level, age, and overall health status. Consuming an adequate amount of protein is essential for muscle repair and growth, as well as overall health and functioning of the body. Choices A, C, and D are incorrect because they suggest protein intake levels that are either too low (A) or unnecessarily high (C and D) for maintaining healthy muscle mass. Excessive protein intake can strain the kidneys and may not provide additional benefits for muscle health beyond the recommended levels.
